Testing of wash water equipment in A-centrifugals at Felixton mill.

TL;DRAbstract

The performance of the A-centrifugal station is of key interest in the final stages of raw sugar production, as it is one of the final unit operations that impacts on raw sugar quality. Good quality massecuite can easily be converted into poor quality sugar by bad curing conditions, and this paper discusses wash water equipment inside batch centrifugals. A survey of the A-centrifugal station at Felixton (FX) raw sugar factory was conducted to establish what equipment exists, with a view to optimising raw sugar quality. This information was used to optimise operations on the A-centrifugals, especially with regards to wash water spray bars and nozzles. A brief trial was conducted at FX with a new multinozzle spray bar, and the results are discussed.
